Improvement in cultivators

DANIEL EDELMAN, OF MADISON, INDIANA.

IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 117,524, dated Augustl, 1871.

To all whom it may concer/n:

Be it known that I, DANIEL EDELMAN, of Madison, in the county ofJefferson' and State of Indiana, have invented' certain Improvements inGultivators, of which the following is a speciiication:

My invention consists in the construction and arrangement of the partsof a cultivator, more fully hereinafter set forth.

Figure l is a side elevation of my machine. Fig.2 is an enlarged view ofone of the side hoes. Fig. 8 is a plan of my machine. Fig. 4 is anenlarged view of the central hoe.

Let A represent the central, and B B side bars of the main frame. Theseare tied together by the cross-bar C. The side bars B B are notstraight, like the central bar, but have angles formed in them, as shownat D D. This angle is such that the rear portions of the bars areparallel with the center bar, and the forward portions converge, so asto form a junction with said bar, as shown. The oblique portions of theside bars are provided with harrow-teeth a a a, and the central bar hasalso a tooth, b. The parallel portions of the side bars are eachfurnished with a hoe, c, see Fig. 2,) and a hoe, (l, of differentconstruction, (see Fig. 4,) is also attached to the rear end of thecentral bar A.

Although I do not claim the hoes separately as my invention, they forman important part of my combination, blade g of the hoe is secured tothe lower end of the standard E by means of a nut and bolt, which allowsthe blade to be reversed when the lower edge becomes dull, the bladebeing exactly alike above and below. The shank of the standard isprovided with .a thread and nut, h, for securing and I will describethem. TheA it to the bar of the machine, and has, also, projectingpoints or teats e e, which bite into the under side of the bar when thenut is Ysrewed tight down, and prevent the standard from turning. Thisarrangement allows the operator to stt the side hoes at any desiredangle with .the line of draft, so as to throw up a large or smallquantity of earth, at pleasure. The barrow-teeth break up the crust onthe surface and prevent the hoes from throwing up clods. The object informing angles in the side bars is to compel the siude hoes c c tofollow in the track of the rear barrow-teeth t a., which they would notdo if the bars were straight. This can readily be s een by inspectingthe plan, Fig. 3. The central `hoe d follows in the track of the toothb. By interchanging the side hoes the earth may be thrown inward, whichis sometimes desirable. G Gr are the handles, and H the clevis. Furtherdescription of these is unnecessary. The side hoes c c are attached tothe standards or shanks E E by a single bolt, x, so that the hoes may bereversed to use the upper edge when the lower one shall have becomeworn.

What I claim as my invention, and desire to secure by Letters Patent,is-

The interchangeable side hoes c c, provided with teats or projections,as described, for adjusting the angle of their position, and withreversible blades or shears, when arranged in combination with thebarrow-teeth a a' a, in the manner and for the purpose herein specied.
